Re: [android-developers] Re: Unable to execute Bluetooth HDP Demo

Hi, thanks to reply.
The problem is that ApplicationConfiguration remain, in spite of calling unregisterAppConfiguration().
I confirmed the demo can communicate with a health device at first time, but second time or later it cann't.
Sometimes Android reboots when I unregister the application config and REregister.
The demo can communicate only once whenever rebooting.

My health devices
blood pressure: HEM-7081-IT
weighing machine: HBF-206IT
pedometer: HJ-720IT

I can communicate currectly with all of these devices and get health data.(only once whenever rebooting)

Hi wambin:

Could you tell more about the exact problem that you are experiencing?
And, what's the medical device that you are using?

Regards.
